REISUEE TUNG SOL 12AX7 -...
Valve manufactured by New Sensor in Russia (like Mullard ). This 12AX7 is very similar in characteristics to the Mullard 12AX7 with low noise, excellent tonal and harmonic response. Guaranteed results from the first moment!
Before the vacuum valves are shipped, they are tested with an Orange Valve Tester VT-1000!
